python - BeasutifulSoup4 中的导航

Question

我需要从几个片段中提取文本(在给定的情况下为“325”和“550”)。我该如何使用 python 3.6.0、bs4、urllib 来解决它。我会将获得的数据添加到 csv 文件中。

<div class="a-row a-spacing-none">
    <a class="a-link-normal a-text-normal" href="https://www.amazon.in/Game-Thrones-Song-Ice-Fire/dp/0007428545">
        <span class="a-size-small a-color-secondary">
        </span>

        <span class="a-size-base a-color-price s-price a-text-bold">

            <span class="currencyINR">  
            </span>
        325
        </span>

    </a>
    <span class="a-letter-space">
    </span>

    <span aria-label='Suggested Retail Price: &lt;span class="currencyINR"&gt;&amp;nbsp;&amp;nbsp;&lt;/span&gt;550' class="a-size-small a-color-secondary a-text-strike">
        <span class="currencyINR"> 
        </span>
    550
    </span>

 </div>

我试过使用以下代码，但无法删除伴随它的 span 标签:

from urllib.request import urlopen as uReq
from bs4 import BeautifulSoup as soup


my_url = 'https://www.amazon.in/s/ref=nb_sb_noss_2?url=search-alias%3Daps&field-keywords=a+song+of+ice+and+fire'
# opening up connection, grabbing thr page

uClient = uReq(my_url)
page_html = uClient.read()
uClient.close()


# html parsing
page_soup = soup(page_html, "html.parser")


# grabs each product
containers = page_soup.findAll("div", {"class":"s-item-container"})
contain = containers[0]
price = contain.findAll("span", {"class":"a-size-base a-color-price s-price a-text-bold"})
current_price = price[0].text.strip()

Answer 1

对于初学者，您可以选择所有具有 currencyINR 类的 span 元素。

currency = contain.find('span', attrs={"class":"currencyINR"})

price = currency.nextSibling.strip()
